Rebirth of the Tech Madman

...

There is only one year left before the return of Xiangjiang, and the intensification of the situation is self-evident.

For example, in terms of personnel, the British civil servants in the Hong Kong government have retired early and returned to their homeland; and the Qinhe line, which has transformed from the old British foreign company Jardine, will inevitably be affected by some restlessness.

Although he had already made complete preparations to deal with it, Mr. Richest Man, who still wanted to manage the face-saving project of buying people's hearts, held a meeting specially for this purpose.

When it was over, he intentionally left behind Zhou Mi who was chatting casually, and casually said, These few days, you have been very aggressive.

Tang Huan said with a smile: I'm also afraid of being missed by people who don't follow the rules. Of course, I have to wipe it off quickly.

Zhou Mi joked: So you also have something to be afraid of.

Believe it or not, you are also on their minds? It's just that it hasn't had time yet. Tang Huan said leisurely: You should have heard how much money Li Bancheng was extorted, right? Bold, how productive is the land?

It seems that everyone should thank you for your anti-violence and safety. Zhou Mi laughed and said, But, how did I hear that Li Bancheng's 1 billion in cash was not saved after all, and all of it was spent?

Perhaps Li Bancheng is superstitious and feels that this money is already unlucky and it is not appropriate to keep it. Tang Huan casually guessed, Didn't it mean that he has already invested the money in the company of his youngest son?

Zhou Mi sighed, I'm just reminding you that the situation in Xiangjiang is very delicate, especially during the period before the return, everyone doesn't want to make waves on the flat ground.

Don't worry, I understand this. Tang Huan nodded, Don't you know my style? Convincing people with virtue, I'm also promoting Bitcoin in private. Get into the pit first.

Zhou Mi asked doubtfully: This Bitcoin, I think the role of money laundering is becoming more and more obvious, what do you think?

It's only just started, so you've already labeled it? Tang Huan shook his head, Only when time goes by can we get a better understanding of this innovative thing.

Zhou Mi pondered: I suggest you to put aside the affairs of Xiangjiang for a while, anyway, there is me, so that the public opinion will cool down.

Listen to people's advice and have a full meal. Tang Huan nodded slightly, The European Space Agency's Ariane 5 launch vehicle is about to launch its first launch. I received an invitation to go over to see the excitement.

...

The warming of Western European countries is reflected in many aspects. In addition to the most famous political and economic organization, the European Union, cutting-edge scientific research institutions are also formed together. For example, CERN, the world's largest particle physics laboratory that has close contacts with Tang It center.

Similarly, the European Space Agency, headquartered in Paris, France, is also a multinational organization with a total of 14 members so far.

Among them, France contributed the most. It offers the location of the European Space Launch Center in French Guiana on the northern Atlantic coast of South America, bordering Brazil.

The rare thing here is that it is close to the equator, only 5 degrees north latitude, which is of great benefit to the rocket launch. The low latitude greatly shortens the distance from the launch point to the orbit point; The energy is small, which increases the payload of the synchronous orbit; at the same time, there is a wide launch arc on the north and east seas; in addition, the population, traffic, and weather conditions are also ideal.

NASA's most important launch center, the Kennedy Space Center, has a similar approach to the site selection. Located on Merritt Island on the east coast of Florida in the eastern United States, it has a north latitude of only 28 degrees; and the Wenchang Space Launch Site, which was opened by China more than ten years later, has a north latitude of 19 degrees.

The work of the European Space Agency covers a wide range of research and development of the upcoming Ariane 5 rocket, which is a major project in charge of it.

In fact, the proponent of this series of rocket programs is France,

Deeper origins can even be traced back to the late World War II, when the Allies plundered Nazi Germany's rocket technology achievements. The relevant technologies obtained by France are mainly related to v2 rockets.

The degree of resource consumption in the aerospace field can be guessed without much thought. If everyone shares the share, it is naturally cost-effective, and the gradual maturity of the structure of the European Space Agency in the 1970s provided this opportunity, so the French National Space Research Center put The Ariane rocket was transferred to the European Space Agency.

As the name suggests, before the Ariane 5 launch vehicle, there were No. 1, No. 2, No. 3, and No. 4, all of which had three stages.

The first successful launch of the Ariane 1 launch vehicle was on December 24, 1979. It was a three-stage launch vehicle developed based on missile technology, followed by the Ariane 2 launch vehicle and Ariane 3 launch vehicle. The No. 1 launch vehicle and the Ariane 4 launch vehicle are all improved models of it.

In terms of geosynchronous transfer orbit payload, the Ariane 1 launch vehicle reached 1,850 kilograms; a total of 11 launches were launched, and 9 were successful.

On November 20, 1987, the Ariane 2 carrier rocket was successfully launched for the first time, with a geosynchronous transfer orbit payload of 2180 kg; a total of 6 launches were carried out, 5 of which were successful.

On August 4, 1984, the Ariane 3 carrier rocket was successfully launched for the first time, and the geosynchronous transfer orbit payload was increased to 2,700 kg; a total of 11 launches were launched, and 10 were successful.

The Ariane 4 carrier rocket, which was successfully launched for the first time on June 15, 1988, has further improved its reliability, and its maximum geosynchronous transfer orbit payload has reached 4,300 kg and is still in service.

It can be said that the performance of these types of Ariane launch vehicles is not satisfactory in terms of payload, for example, it is inferior to China's Long March-2 launch vehicle.

Therefore, the newly designed Ariane 5 launch vehicle has high hopes. Its research and development took ten years and 7 billion yuan in funds, and the minimum geosynchronous transfer orbit payload has reached about 6100 kilograms.

The Ariane launch vehicle is funded by 24 shareholders from 10 European countries. It can be said that the interests are evenly shared, so it has attracted great attention.

Tang Huan is also very interested in the launch vehicle itself. Gein's current launch cost is cheap in the tens of millions of dollars, and if the Ariane 5 launch vehicle is successfully launched, that means, The addition of an option in the international market is definitely a lot of benefits.

Even if he wanted to get close to the European Space Agency, a big financier with thousands of employees and an annual budget of billions of dollars, the richest man would not travel all the way to French Guiana in South America. He only needs to visit its location in France The headquarters in Paris will do just fine.

With everything in place, the countdown to the Ariane 5 launch began.

Tang Huan and others at the European Space Agency headquarters in Paris, France, can clearly see the scene of the European Space Launch Center in French Guiana on the big screen.

At 12:34, the Ariane 5 carrier rocket ignited, dazzling flames spewed out from the bottom, and the rocket left the ground and soared into the sky.

After 5 seconds, everything works fine.

After 10 seconds, everything works fine.

After 20 seconds, everything works fine.

After 30 seconds, everything works fine.

...

Inside the headquarters of the Arianespace company in the southern suburbs of Paris, the tension and excitement are clearly increasing in the ratio of the latter.

Some people, like Mr. Richest Man, who participated in the satellites carried by this launch, also whispered with ease.

...

After 35 seconds, everything works fine.

Suddenly, the rocket that pierced the sky straightly, deflected 90 degrees to the left inconceivably, its posture changed from vertical to horizontal, and then exploded into fireworks all over the sky.

Gene Luton, general manager of Arianespace, which operates and sells the Ariane rocket, suddenly looked sour when it appeared that the rocket was carrying a communications satellite worth $500 million. Including the rocket itself, $600 million was burned in the blink of an eye.

Such a tragic scene not only made the people at the Paris headquarters feel mournful, but also the on-site visitors of the European Space Launch Center in French Guiana, as well as countless viewers watching the live TV broadcast, all lamented that this firecracker is really expensive!

...

When shaking hands and saying goodbye, Tang Huan said to Gene Luton seriously: As far as I know, the programming language used by the software control system of the Ariane 5 launch vehicle is ada. He has rich experience, and if possible, he is very willing to contribute a little to the accident analysis.”

Thank you Don for your kindness. Gene Luton replied with a sad face, We will think about it carefully.

...

For the failure of the first launch of the Ariane 5 carrier rocket, among those who grieve, the richest man is definitely not on the list.

Therefore, Tang Huan continued to eat and drink as usual, and play as much as he wanted. This year's French Open, Steffi Graf once again entered the final, just to enjoy it.

Now, there is only one thing that can defeat the queen of tennis, and that is the injuries accumulated over the years in his career. Although the richest man took precautions when Steffi Graf was growing up, the laws of nature are the laws of nature.

Fortunately, Steffi Graf's injury problems this year are not obvious, and his competitive state is also quite good.

According to this trend, Steffi Graf has almost no problem surpassing those career historical records set by tennis predecessors such as Margaret Court in the early years.

During the chat, Jin Xing and Jin Guo, who are the strongest among all the sons of Tang in the same age group, even though they have just turned 5 years old, shook Tang Huan's arm, pointed at the TV, and kept asking curiously, Dad, Dad Why, halfway through the flight, did the rocket turn around and explode?

The richest man smiled and said, Not only you want to know, everyone wants to know what's going on now, but unfortunately, the reason has not been found yet?

The child who thought that his father was omnipotent asked naturally, Father, why are they so stupid, why don't you ask for your help to find the reason?

Tang Huan laughed heartily, Who knows? Maybe they want to keep technical secrets, or maybe they can't save face...

...

Arianespace, which operates and sells the Ariane rocket, is funded by 24 shareholders from 10 European countries. Among them, France has the largest number of shareholders, with a shareholding ratio of more than 60%; followed by Germany, with 2 shareholders, and a shareholding ratio of more than 18%; followed by Italy, Belgium, Switzerland, Sweden, Spain, the Netherlands, Norway, Denmark.

It is of course convenient for everyone to cook together, but once the meal is cooked, there will be a lot of confusion. It is not so easy for every shareholder to accept failure calmly.

Under tremendous public relations pressure, all partners of the Ariane 5 launch vehicle, including the European Space Agency, the French National Space Research Center, Airbus Group, and Arianespace, quickly made a unanimous decision. Introduce an authoritative third party to assist in the accident investigation, so as to give everyone a clear explanation.

So, Tang It, who had taken the initiative to say hello before, naturally became the guest of honor.

Mr. Richest, who was playing with the children with a small tennis racket, was not pretentious when he got the invitation, and immediately said that the most elite technical team would come over soon. Before that, let me take a rough look at the software code of the control system. If the investigation can reveal the truth before the final of the French Open, everyone will appreciate it in a relatively relaxed mood, right?

17 years ago, Tang Huan, who developed the world's first spreadsheet program grid, is known as the father of spreadsheets. But there is no trace of the works, and I don't know if Jiang Lang's talent is exhausted.

In fact, of course, the richest man has not forgotten the housekeeping ability to bring himself the first pot of gold. Take Zheru's own programming and development general environment zeroone_ as an example, and he is very familiar with it!

Under the accompaniment of the staff, Tang IT used zero_one_ to import the ADA language code of the Ariane 5 launch vehicle.

Although aerospace is a huge project, it does not mean that the computer embedded system used is allowed to be bloated. You must know that in space, energy is extremely precious, and any action must be efficient.

Although there are a lot of software codes for the control system of the Ariane 5 launch vehicle, it is really not comparable to the scale of Zheru's office software suite.

Tang it casually typed a command to let zerone_ highlight and track the conversion codes of different data types.

Not long after, he pointed to one place and said earnestly: The conversion from 64-bit floating-point numbers to 16-bit integers here is very suspicious!
